fix(authoring): commit colour changes after picking - #488
Conversation
📝 WalkthroughWalkthroughShape color controls now update the selected visual component during picker interaction. Final values commit one history entry after pointer release or outside clicks. Local shape state refreshes when the selected component or rendered visual component changes. ChangesShape preview editing
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to A colour interaction that returns to its starting colour can leave stale state behind, causing a later colour change's undo action to revert an unrelated shape modification. This is a concrete correctness risk, so the PR should not merge until the final colour interaction is always committed safely. Sequence Diagram(s)sequenceDiagram

Finalize every pending picker interaction.
When a drag returns to its initial colour, Line 42 skips onChange. ShapeSection has already captured previewStart during preview, and it clears that snapshot only in commitPreview. A later colour commit can then use the stale snapshot as its before state and make undo revert an unrelated property change.
Call the final callback whenever hasPendingChange.current is true. updateHistory already suppresses a no-op record.
Proposed fix
- if (colour !== committedColour.current) {
- onChangeRef.current(colour);
- committedColour.current = colour;
- }

Issue
Changing a shape's fill or stroke colour currently creates a history/autosave entry for every intermediate colour while dragging across the colour picker. This means a single colour selection can require multiple undo actions to return to the original colour.
Solution
Updated the colour picker flow so that:
Risk
Low, but Hartej forgetting to assign issues to me is high.
